Physicochemical Properties of Honey Produced in the Homesha District of Western Ethiopia This study was conducted to characterize honey produced in the Homesha district in Western Ethiopia. The effects of location and hive type on the quality of honey produced in the area were assessed. A total of 20 honey samples were collected from four locations in the district. The overall mean (±SD) contents of reducing sugars, sucrose, pH, moisture, ash, hydroxymethylfurfural, acidity and water-insoluble solids of the honey samples analyzed were 65 ± 3.02%, 6.1 ± 3.4%, 4.02 ± 0.26, 16.4 ± 1.07%, 0.17 ± 0.07%, 1.8 ± 0.24 mg/kg, 23.9 ± 7.4 meq/kg and 0.09 ± 0.14%, respectively. The sucrose content of honey samples purchased from the market was significantly higher (p<0.05) than the sucrose contents of honey samples collected from other locations. Hive type significantly (p<0.05) influenced the contents of moisture, HMF and water-insoluble solids of honey samples. It can be concluded that honey produced in the Homesha district is of good quality and can meet the national and international market demands.

Fishing tourism is one of the modern types of tourism that is aimed at meeting the needs of a certain segment of tourists in fishing. This type of tourism is organized by special enterprises to favorable places for fishing. Fishing tours in most cases include specialized services such as: fishing license, tackle rental, boat rental, instruction and joint fishing with a qualified fishing guide, as well as services aimed at preserving and preparing the fish caught. Such countries as Finland, Norway, Egypt, Namibia, South Africa, Iceland, Sweden, Slovakia, Thailand and Israel occupy high positions in the international market of fishing tourism and are famous for their fish resources. As for fishing tourism in Russia, the demand for fishing tourism is currently increasing. Tourist companies are engaged in expanding the geography of fishing tours and improving the quality of service, which affects the increase in demand for this type of tour. The analysis of the potential of the Astrakhan region, carried out in the article, allowed us to identify opportunities for the development of organizational fishing tourism.

Honey is one of the oldest sweetening foods and has economic importance, making this product attractive to adulteration with cheap sugars. This can cause a critical problem in the honey industry and a possible health risk. The present work has the aim of evaluating the authenticity of honey commercialized in two different provinces of Ecuador (Pichincha and Loja) by performing physicochemical and spectroscopic analyses. For this study 25 samples were collected from different places and markets and characterized by water, sucrose, reducing sugars and electric conductivity measurement. Also, their Raman and Infrared (IR) spectra were recorded and analysed using a Principal Component Analysis (PCA) in order to verify the quality of the honeys. In addition, a screening of several pesticides was performed in order to verify possible chemical threats to human health and honey bees. It was found that 8 samples have a deviation from the Standard established parameters. Two of them have a high difference in the content of sucrose and reducing sugars, which are located deviated from all the other samples in the PCA of the applied vibrational spectroscopy (IR/Raman), shaping two clear clusters. The results show that Raman and IR spectroscopy is appropriate techniques for the quality control of honey and correlates well with the physicochemical analyses.

Adjuvants have been used for decades to enhance the immune response to vaccines, in particular for the subunit-based adjuvants. Physicochemical properties of the adjuvant-protein antigen complexes, such as size, morphology, protein structure and binding, influence the overall efficacy and safety of the vaccine. Here we show how to perform an accurate physicochemical characterization of the nanoaluminum–ovalbumin complex. Using a combination of existing techniques, we developed a multi-staged characterization strategy based on measurements of increased complexity. This characterization cascade has the advantage of being very flexible and easily adaptable to any adjuvant-protein antigen combinations. It will contribute to control the quality of antigen–adjuvant complexes and immunological outcomes, ultimately leading to improved vaccines.

Pre-harvest sprouting (PHS) severely reduces rice grain yield, significantly affects grain quality, and leads to substantial economic loss. In this study, we aimed to characterize the physicochemical properties and processing quality of the Garumi 2 flour rice variety under PHS conditions and compare them with those of the Seolgaeng, Hangaru, Shingil, and Ilpum rice varieties and the Keumkang wheat variety. Analysis of the molecular structure of starch revealed uniform starch granules, increased proportions of short-chain amylopectin in DP 6–12 (51.0–55.3%), and enhanced crystallinity (30.7–35.7%) in rice varieties for flour compared with the Ilpum cooking rice variety. PHS significantly altered the starch structure and gelatinization properties of Garumi 2. It also caused surface pitting and roughness in Garumi 2 starch granules and decreased their crystallinity. Collectively, the findings of this study provide important novel insights into the effects of PHS on the physicochemical properties of Garumi 2 floury rice for flour.

Objective: To evaluate the industrial quality of three sugarcane cultivars in a template cycle at the supply area of “Santa Rosalía de la Chontalpa” sugarcane mill. Design / Methodology / Approach: An experiment was established under a factorial design 3x3 (3 cultivars: CP 72-2086, MEX 79-431 and MEX 69-290; x 3 sampling dates: 330, 390 and 450 DDS, Spanish equivalent for days after sowing) on an Eutric Fluvisol soil. In each plantation, a sample of 10 stems with three replications was collected to determine the industrial quality by polarimetry. Results: The industrial quality of the evaluated cultivars only differed statistically in terms of the percentage of purity, MEX 79-431 was the one that presented the lowest value for this variable. At 450 DDS, the highest value was observed for °Brix (17.28), POL percentage (14.92), purity (86.44%). The values obtained in the present study for the quality of juice in the evaluated cultivars are within the range of the standard values established for Mexico. Limitations / Implications: Polarimetry is still the method used by most of the sugar mills in Mexico, even if other more environmental-friendly methodologies exist. Findings / Conclusions: The trend line that best fit to MEX 69-290 and MEX 79-431, for °Brix, POL and purity, was a linear polynomial and to CP 72-2086, a polynomial quadratic. Fresh stems and reducing sugars showed best fit with an inverse polynomial. °Brix presented strong and positive correlation with POL (R = 0.99**); and strong and negative with reducer sugars (R = -0.95**) and fresh stem humidity (R = -0.91**).

Physicochemical Properties Of Soils

In this study, two sites from tea and apple growing sites were collected from Pyay village and Nine Mile village, Mindat district, Chin state of West Myanmar under a humid subtropical climate. The results of physicochemical properties of observed soils were neutral pH, favorable moisture, silty clay loam texture, very high content of organic carbon, organic matter and total nitrogen. However, the tea growing soil was very poor in phosphorus and potassium content. Moreover, both soils lack of available potassium. The content of heavy metals in both soils was not varied from each other and followed the order: Fe (iron) > Cu (copper) >Zn (zinc) > Pb (lead) > Cr (chromium) and was below the maximum allowed concentrations (MAC). Therefore, the studied soils are generally favorable for cultivation under the condition of application of phosphorus and potassium fertilizers. However, due to the regular application of fertilizers and pesticides, it is necessary to monitor these soils for PTE levels. Further research is recommended, which must include analyses of the physicochemical properties of soils to a two depths of 0-30 and 30-60 cm, especially for the area where fruit plants are grown. In addition, higher density of soil samples and sub-samples are necessary to produce a reliable dataset that will allow proper statistical analysis.

В условиях двухлетнего полевого опыта на растениях льна-долгунца исследовано влияние внекорневой подкормки боросодежащими хелатными комплексонами на продуктивность и качество льнопродукции. Изучено действие борат-иминодисукцината (В-ИДЯК) и борат-этилендиаминдисукцината (В-ЭДДЯК) в сравнении с борной кислотой и борат-этилендиаминтетраацетатом (В-ЭДТУК). Исследования выполнили в 2019–2020 гг. в однофакторном полевом опыте. Установлено, что наиболее эффективное и экологически безопасное влияние оказывает внекорневая подкормка посевов льна-долгунца хелатным комплексом В-ЭДДЯК. При внекорневой подкормке часть препарата, попадая в почву, мобилизует также другие микроэлементы, тем самым оказывая стимулирующее действие на растения. Полученные результаты показали, что внекорневая подкормка боросодержащими соединениями существенно повлияла на накопление биомассы льна-долгунца. Выявлена положительная динамика влияния боросодержащих комплексов на прохождение фенологических фаз во второй половине вегетации. Внекорневая подкормка растений ускорила цветение льна, которое наступало раньше на 2–3 дня по сравнению с контролем. Применение подкормки хелатными боросодержащими комплексонами способствует росту урожайности растений, повышению качества продукции, в части улучшения физико-химических свойств льноволокна. Прибавка урожая к контролю составила: по льносоломе – 8,3–15,7% (3,2–6 ц/га), семенам – 38,4–56% (1,2–1,9 ц/га). Техническая длина соломы была выше у всех вариантов опыта на 8,5–10,4% по сравнению с контролем. При этом увеличивались: выход луба, прочность, пригодность и номер льносоломы. Увеличение содержания луба составило от 1,6 до 4,5%. Under the conditions of two-year field test, the effects of foliage application with boron-containing chelate complexones on the productivity and quality of flax products were investigated on long-stalked flax plants. The effect of borate-iminodisuccinate (B-IDSA) and borate-ethylene diamin-disuccinate (B-EDDSA) in comparison with boric acid and borate-ethylene diamintetraacetate (B-EDTAA) was studied. The researches were conducted in 2019–2020 in a single-factor field test. It has been found that the most effective and environmentally safe influence is exerted by foliage application of long-stalked flax sowings with the chelate complex B-EDDSA. In foliage application part of the preparation falling into the soil also mobilizes other trace elements, thereby exerting a stimulating effect on plants. The obtained results showed that foliage application with boron-containing compounds had a significant impact on the accumulation of long-stalked flax biomass. Positive dynamics of boron-containing complexes influence on phenological phases passage in the second half of growing season has been revealed. Foliage application of plants accelerated flax flowering, which occurred earlier by 2–3 days compared to control. The use of top-dressing with chelated boron-containing complexones contributes to the growth of plant yields, an increase in the quality of products, in terms of improving the physicochemical properties of flax fiber. The increase in the yield to control was: according to linen straw – 8.3–15.7% (3.2–6 c/ha), seeds – 38.4–56% (1.2–1.9 c/ha). The technical length of the straw was 8.5–10.4% higher in all experience variants compared to the control. At the same time the output of the bast, the strength, suitability and number of the linen straw have been increased. The increase in bast content ranged from 1.6 to 4.5%.
